riak-admin cluster commit not mentioned in "adding nodes" section.

The section in the docs about [adding nodes in 1.2.1](http://docs.basho.com/riak/1.2.1/cookbooks/Adding-and-Removing-Nodes/#Joining-Nodes-to-Form-a-Cluster) does not mention issuing a `cluster commit` command. Even if you read through ["The Node Join Process"](http://docs.basho.com/riak/1.2.1/cookbooks/Adding-and-Removing-Nodes/#The-Node-Join-Process) it does not mention commit. 

You must read to the "Removing Nodes" section before commit is mentioned, so if I was a new user I might not read that section and be really puzzled why my nodes aren't joining.
